To all whom it may concern:

'Be it known that I, JANE LoUDo-N WALKER MURRAY, a subject of the Kingof Great Britain and Ireland, and a resident of Craiglockhart, in thecounty of Mizdlothian, Scotland, have invented a new and useful Piece ofFurniture Convertible for use as a Bed, Couch, Bath-Chair, or the likeof which the following is the specification? The invention relatesto'furniture of the type'which' is: convertiblefor use as a bed, acouch,acarrying chair orithe like, or one or more of them, and which haslacentral or sea-t member, a headmember pivoted-t0 one end thereof, and aleg. member pivoted to the other-fend, the leg mfember having insomecases' a foot member hinged in turn to 'itythe head an'd leg membersbeingso "articulated'together that on the head member being eitherraised or loweredthe position ofthe leg member is also adjusted; and'theinvention has for its object to provide an improved piece of furnitureofthis type capable of use also'asa bath chair or a stretcher, and simplein construction considering its variou's capacities, of light sides" ofthe central. structure A an weight, and easily operable; a

An illustrative but not limitative example of the piece offfurniture isshown on four accompanyin'g sheets ofexplanatory drawings. In thesedrawings Figure 1 and Fig. 2 are respectively a plan and a sideelevation, with certainparts omitted to avoid confusion, of thestructureas a bed, and Fig.3 is a side-elevation showing the structurearranged as a bath chair, While Figs. 4 and 5 are respectively a planand a side elevationof details hereinafter referred to,

the last mentioned figure being drawn to an enlarged scale.

Fig; 6 is a perspective showing the rectangular shape of the frames Jand rest or support E, E E f As shown in the drawings there is provideda central braced strueture'A provided with supporting ,postsA andforming approximately the central part of the bed and ;theseat of thebath chair when the apparatusis soused; structure is pivoted what may'betermed a 'head member or'frame A consisting of two To one end ofthiscentral rods or tubes pivoted at" A on'the oplpesite e a 9 nested'tegether' attheze upper ends by a convenient manner.

The central structure A, thesubsidiary head member B the leg member B and the footmember B are allshown as fittedw-ithi ordinary metal lath mattresses B for the sake ofclearness in drawing, though'of course spring or other convenient formof mattresses may beemployed, and these are upholstered in any On-eachside of the subsidiary head member B is a wormwheel quadrantC (Fig, 5)gearing with a worm C on a spindle C turning in bearingsin a. bracket Con the central-structurevA. These spindles C? have on them bevel pinions0 each of which gears wither-similar bevel pinion C on the opposite endsof aitransverse shaft@ which maybe fitted with a handle or with ahandwheel, (not shown) easily accessible to the occupant. Thesubsidiaryhead member B has on it catches D vby means of which it may belocked to the main head member A When these catches are free'andthe-parts in the bed position, on

- operation of the'gearing the subsidiary head member B alone may beadjusted to any desired angleand thus form a bed back rest. When howeverthesubsidiar y head member B is locked by the catches D to the main headmember A on operating the gearing these two members are raised togetherand, as the main head member A the leg member B and the foot member Bare 'artic ulated to one another as hereinbe'fore described, upon thehead member A being raised into an angled position-the-leg member B islowered accordingly, -and tl16f fOOt member B substantial-1vmaintaining-its horizontal position fi'n'ally becomes thefoot heels G inthe operating gearing are the structure are securely held in anyposition to which they are adjusted. The chain lines in Fig. 2 show theparts in the position ,they would. assume when adjusted to practicallymidway'between the bed' and bath chair positions, in which position theyform A What may be termed an inclined couch. The leg member B has partsextending beyond its point of pivoting A to the central structure Atoward the head member A and these parts are connected by links D to the.;-head member. These links form arms in the bath ohairposition and alsoserve to secure the parts rigidlyin their various positionsgFAlong thesides of the various'mem- .bers are arranged .flaps D which may beturned shorizontally as shown in Fig. :1 to increasexthe eflective widthof the bed, or theymay be turnedup as'shown in Fig. 3 "tofproteot andinclose the, occupant when ,thei-apparatus is in use as a bath chair.:Means such-as thumb screws similar to. J Fig.2, but for the sake ofclearness, not shown, are' provided lforwlocking the flaps D in anydesired position. The footmember B carries at opposite sides upstandingslotted tubes D braced togetherito'form the foot'ofthe bed, and rodsDcarrying pawls D slide in these-tubes so that they may be 30 lowered tosupport that member whenithe apparatus is in use as a bed, or raisedwhen that memberbecomes the foot-rest ofa bath chair. The pawls D engagecatches on the ,1 tubes D and hold the rods D* in either position. Tothe subsidiary head'member-B is attached, a device forming a book restand table support. This device is only shown in -Fig. 3 by chain linesfor the sake of clearness xin drawingyand it consists of two rods Ehinged atone end to the opposite sides of the subsidiary head memberand.v having hinged to their opposite ends two other rods E ,tofwhich inturn is hinged a U-shaped rod E? forming in the position shown the :thesupporting rod E is turned u against .the rodsE andthe whole turneoverso that it extends down the back of the subsidhead member B At thehead end of the structure there is also a frame, the side members G ofwhich run on, guides G -(Fig. 5) on .the. central structure A. A rack isformed on each side memberjwith which there gears a pinion Gr on atransverse shaft G the, ends of-which are squared to receive a handle sothat the I .framevmay be moved outward or inward. 7 This frame hasposts-H bearing upon. the floor and-adapted to support the apparatusWl1611 it is in bed-form.
